Title: Method of manufacturing semiconductor device
Inventor: FUJII YUJI
IPC: H01L29/12
Filed: 2017-09-22
Abstract: To manufacture a semiconductor device having excellent characteristics.SOLUTION: A method of manufacturing a semiconductor device according to the present invention comprises the processes of: forming a metal film (Ni film) MT on a bottom face of a contact hole (C1, C2) having an SiC-made region exposed on a bottom face of the semiconductor device; and performing a heat treatment to form a silicide film on the bottom face of the contact hole (C1, C2) through silicide reaction between the metal film MT and the SiC-made region. The heat treatment process is a process of irradiating a surface of an SiC substrate with laser light. By performing annealing using a laser with a wavelength of transmitting Sic and absorbing metals (such as Ni) as a heat treatment in forming a silicide film, generation of a carbon layer due to segregation of carbon (C) in Sic can be suppressed, thereby suppressing increase in contact resistance and contact failure.SELECTED DRAWING: Figure 11
